SPOT Welding

SPOT Welding

SPOT welding can be used for material from 0.5 to 3mm in thickness. The contacting metal surfaces are joined together by the heat obtained from the resistance to electric current – the process is applied using two shaped copper alloy electrodes that concentrate a welding current into a small “spot” and to simultaneously clamp the sheets together. Forcing a large current through the spot will melt the metal and form the weld.
